What is batch image compression?

Batch compression applies the same compression settings to multiple image files simultaneously, saving time compared to processing each image one by one.

Can I batch compress different file types together?

Yes. You can mix JPG, PNG, and WebP in the same batch upload. Each file compresses according to the quality setting.

Will all images in the batch have the same output file size?

No. Output size varies because different images compress differently depending on their content. All images receive the same quality setting, but file sizes will differ.

Is batch compression as good as individual compression?

Yes. The same compression algorithm applies. Batch mode simply automates the process for multiple files.

How long does batch compression take?

Processing 10 images takes 5–15 seconds on a modern desktop. 50 images may take 30–60 seconds. Mobile devices take longer.

Can I re-compress the batch if I want different quality?

Always re-compress from the original files, not from already-compressed versions, to avoid accumulating quality loss.
